I understand. I'd avoid using terms like "nature intends", because it implies nature has a consciousness and is capable of intentions. It doesn't and isn't. And it shouldn't imply that the harsh way to live is the "right" way to live. :3

Right. That was just a figure of speech. :-P Also, I don't think there's really any "right" way to live... there are just ways to live. Right or wrong is determined by the scociety that we live in. I don't think it's right that they eat dogs in certain parts of Asia, but that's their culture and they do it.
